All Macros in particular sole structure are not necessarily formed by the spring plate material of identical type or the damping layer material of identical type.Such as, a Macro of footwear sole construction can comprise the latch plate formed by the first composite and the first damping material, and another Macro of this footwear sole construction comprises the latch plate formed by the second composite and the second damping material.Comparable second composite of first composite is hard, or vice versa.Comparable second damping material of first damping material is soft, or vice versa.Similarly, single Macro can comprise the latch plate formed by multiple material and/or the Damping material layer formed by multiple damping material.Such as, latch plate can have fortifying fibre (such as in heel and/or arch area, carbon, glass and/or polymer), to provide additional rigidity, or (or dissimilar) fortifying fibre of larger quantity can be had in heel and/or arch area.As another example, latch plate can need in some regions of more large rigidity (such as, heel and/or arch of foot) thicker wherein.As further example, latch plate can be formed by the fluoropolymer resin (or mixture of fluoropolymer resin) of a type in a region, and is formed by dissimilar fluoropolymer resin (or mixture of fluoropolymer resin) in another region.Resin density also can change at whole latch plate.These features (such as, the enhancement of change, thickness, resin content and/or density) and/or other features also can be combined in single latch plate.In addition, in some embodiments, latch plate can have heterogeneity more firmly or otherwise in the region except heel area.Such as, and as noted earlier, inner side or outside can be harder.Single Damping material layer also can comprise multiple material and/or otherwise change in the zones of different of footwear sole construction.Such as, more intensive foamed material can be used for wherein needing in the region of additional stiffness.As another example, not too intensive foam can be used in some inside region, to increase the sensation of " tilting (banked) " during tangential motion.

The configuration of the Macro in the footwear sole construction according to various embodiment and/or quantity can change, so that the footwear sole construction that acquisition is specific purpose (such as, particular athletic activity) and regulates.Such as, some users may need less buffering and like having the footwear of lower overall height.For the embodiment of this type of user design only may comprise two Macros.As another example, material alterable and/or change in shape, to prevent from excessively revolving front or other less desirable pin motions.As further example, the calmodulin binding domain CaM (such as, the width in the such as region of center strip 44 and 45 and/or length) between the Macro of undamped material can increase or reduce, to change the rigidity of footwear sole construction.Material and other configurations of one or more layers can change the people adapting to Different Weight.The material of one or more layers and other configurations also can change the people adapting to the individual style with the activity that participation designs for footwear.Such as, a sporter may trend towards the running carrying out " stamping one's foot " style.The footwear of type games person design can have additional layer and/or harder layer in heel area for this reason.Another sporter may trend towards more weight to be placed in the his or her forward foot in a step.The footwear of type games person design may need less heel rigidity for this reason, but need more to support or be buffered in the forward foot in a step.

With with wherein can suppress, in the similar mode of selected frequency range internal vibration, also can select the latch plate of Damping material layer and/or different layers, so that conditioning sole structure adapts to the activity of certain limit in conjunction with the constrained layer damping of multiple level.Such as, first Damping material layer (such as, the layer similar with the layer 21 of footwear 1) can be formed by relative soft material, second Damping material layer (such as, the layer similar with the layer 22 of footwear 1) can be formed by more solid material, 3rd Damping material layer (such as, similar with the layer 23 of footwear 1 layer) can be formed by even more solid material.When wearer to participate in that such as leisure is taken a walk etc. relatively light movable time, softer ground floor can provide comfortable to wearer.When wearer participates in more violent movable such as such as straight line running, the more solid second layer can additional support.When wearer participates in stricter movable such as the running such as frequently with the change of tangent or other directions, even more solid third layer can provide further support.In other embodiments, the Damping material layer of various combination can be used, so that conditioning sole structure is used for the activity of desired scope.

Alternately the latch plate for various layer can be selected and/or change to (or also), so that conditioning sole structure in a similar fashion.Such as, a latch plate can be formed by glass fiber compound material, and another latch plate can be formed by carbon fibre composite, such as, to provide different-stiffness, flexibility, bending and/or response characteristic.(such as, give in given layer and/or from layer to layer) also can change latch plate thickness, to provide different qualities, such as, and different-stiffness, flexibility, bending, response etc.).

Additionally or alternately, between the various layers of footwear sole construction (such as, via adhesive or cement, via mechanical connector, via fusion techniques etc.) feature that is attached can change (such as, direct attachment between direct attachment between adjacent springs plate and/or plate and contiguous Damping material layer), to control or " sensation " and/or other characteristics of meticulous conditioning sole structure.As some examples more specifically, creating the amount of the surf zone of described attachment, the position of described attachment and/or the type of described attachment can change or control, with change or conditioning sole to " sensation " of wearer or other characteristics.As example additional in addition, surf zone and/or the position of the attachment between adjoining plate and/or between plate and contiguous Damping material layer can change, to control the rigidity characteristic (comprising torsional rigidity, linear rigidity) of footwear sole construction; To control the flexibility or bending of footwear sole construction; With the footwear front area controlling footwear sole construction relative to the torsion of the heel area of footwear sole construction and/or flexibility; To promote that (or suppression) revolves front or supination; To control the response etc. of footwear sole construction.

In some embodiments, the additional connection between Macro can be increased.But as an one example, the latch plate of different Macro can engage, to increase the rigidity in some region along its outer peripheral part.The latch plate of contiguous Macro also can lack direct connection each other.Directly be attached to the second latch plate 12 unlike wherein center strip 45 and center strip 44 is directly attached to footwear sole construction 10 embodiment of the first latch plate 11, other embodiments can comprise the material between intervention two latch plates.Such as, the additional band of reinforcing material can be incorporated into all or part of center strip on the inner surface of Macro A.Then, this enhancing band can be incorporated into the corresponding part of the outer surface of the latch plate of adjacent Macro B.The corresponding part of the outer surface of the latch plate relative to Macro B is fixed by the center strip of Macro A, but offsets by the thickness strengthening band.In some embodiments, the Damping material layer between two latch plates can extend across the whole width of footwear sole construction.Such as, Damping material layer can two latch plates completely in separation center region, instead of as the direct contact between the latch plate seen in the central area (Fig. 4 A1 and Fig. 4 B1) of footwear 1.

In the embodiment of footwear sole construction 10, the interior outside of Damping material layer 22 is attached to latch plate 11 and 12 respectively.Similarly, the interior outside of Damping material layer 23 is attached to latch plate 12 and 13 respectively.This is described situation not necessarily.Such as, in some embodiments, one or more Macro can comprise wherein Damping material layer and is not joined to the latch plate of one of adjacent springs plate.Such as, and with reference to Fig. 4 A1, alternate embodiments can comprise the second Macro, wherein the second Damping material layer (in the position similar with the second Damping material layer 22) is not joined to the outer surface of (similar with the latch plate 11) latch plate directly over being positioned at, and the unique connection between Macro can be attached to similar fixing of latch plate 11 part with the region 44 of wherein latch plate 12 between latch plate.Similarly, 3rd Damping material layer (in the position similar with the 3rd Damping material layer 23) of the 3rd Macro can be not joined to the outer surface of (similar with the latch plate 12) latch plate directly over being positioned at, and the unique connection between Macro can be attached to similar fixing of latch plate 12 part with the region 45 of wherein latch plate 13 between latch plate.
